Hi!

Use the SINC function included in the package pst-math
<http://www.ctan.org/tex-archive/graphics/pstricks/contrib/pst-math/):

\documentclass{article}
\usepackage{pst-plot}
\usepackage{pst-math}

\begin{document}

\psset{xunit=0.5cm,yunit=2cm}
\begin{pspicture}(-10,-0.3)(10,1)
   \psaxes{->}(0,0)(-10,-0.3)(10,1)
   \psplot[plotpoints=200]{-10}{10}{x SINC}
\end{pspicture}

\end{document}
